Crank Shaft Damage

I had a local shop change out my timing belt. A few hundred miles later I had a slapping noise. This time I took it to Toyota because they are closest to my house and they advised my crank shaft is damaged (see photos for full write up).
Toyota wants to replace the whole dang crankshaft. Seems excessive to replace entire crankshaft but I won’t pretend like I know more than mechanics or any of you wiser folks.

So here’s my question: The local shop advised they could repair the crankshaft with a sleeve. Does anyone have any experience or knowledge with a crankshaft sleeve being a legitimate long term and durable fix?(I’ll get a new pulley/harmonic balancer in there as well.)

Truck is 2004 Tacoma 5vzfe

thanks for any insights!
** also the photo shows a service price of 1,793 but they actually quoted me $9,000.

 

I would seek out any advice @Speedytech7 might have. Off the top of my head I’d say Toyota is trying to make a quick $9k off ya.

 

Yeah that was my initial thought as well. I’ll reach out to them thanks!

 

This is whats happened to your crank

there is no way to resleeve that....short of butcher welding the key in permanently


the sleeve they're talking about is a seal saver most likely

and dont think that's will do jack

 

If miles is low....its worth putting in a new crank

otherwise I'd buy an engine with a warranty

which you can do for half of the toyota dealer
and they are gonna do book time......so the dealer job will be hurried at best

welcome to the club.......very exclusive club......you have to bleed lots of cash to get in this one

 

Is the keyseat damaged or was only the key filed down? Hard to see from the pics. If the seat isn’t wallowed out you could replace the key and balancer.



The sleeve would just be a fix for the outer surface of the crankshaft from what I can tell from what the independent shop was saying they could do.

But yeah you need to take more pics around that crank snout...

and see what the key looks like.....maybe its just sheered off
and not wallowed out



As I've said....when you stab a new crank pulley.....you got to prep it and take the sharp edges off the keyway.....or pay the price

whole system is so tight...its easy to mis-stab and catch the leading edge on the key.....,and once you give it the 200LB crank bolt....damage is catastrophic

 

when you buy these trucks.....try to test the HB

load the engine up with everything you can.....turn on ac....while turning hard...
rev it.... you're trying to over load the pulley

head gasket is cheap compared to this


From your HB it looks like try tried to use JB weld........and then quickly sold it
or the whole key is sheered off in there

 

here’s some better photos of the key way. Looks like the key and seat might be alright?

 

I would not allow a sleeve to be put on my truck and call it a solution. The sleeve will be a bandage and technically, release the shop of any liability. You took the truck in for service and without a sleeve, why leave with one in place?

I would, at a minimum, request the shop put in a new crankshaft/HB etc or a short block with proof of work. If the shop insists a sleeve is a solution, I would reach out to your local BAR (Bureau of Automotive Repair) representative.

Shes at 219k, low for a Toyota…haha
At this point if the local shop doing timing belt job improperly is the reason for the crank shaft issue then I’ll be trying to put the bill on them.

 

The Toyota suggested repair might be expensive.. but they're not the ones that fucked it up. Yes it's 9k but complete replacement is the correct repair..

I wouldn't want a sleeve either. The indy shop needs to suck it up or be more careful if they're going to do timing belt jobs

 

Very good point.

 

you can see where the key slot is majorly damaged in the HB.....
so I think its been like this for awhile


They should of flagged it and showed you

.....but everybody's in a big freakin hurry.....cars were probably backed up

by not showing you.....they libeled themselves



the reason if you cant work on these....you're taking your chances every time any one else does something to it

like I said......big hurry......people now a days will shoot you if you cut em off

 

My understanding is, per BAR, you have to give the shop an opportunity to “right their mistake” or agreed upon a solution. Taking the vehicle to another shop and have another shop foot the bill will end up costing you money and you wouldn’t be able to collect because there was no agreement in place (writing).

 

You think it’d take longer than a thousand or so miles to cause this kind of damage?

 

interesting, good to know. Frustrating because at this point I don’t trust the quality of their work. They can’t do a timing belt properly let alone replace the entire crank shaft with seals, bearings, etc.

 

Sometimes the cheap shop is the expensive shop

 

believe that was all mickey moused before

when they disturbed that it was only a matter of time


how long have you owned.....how many miles total have you put on it since purchase

 

yeah I hear ya. I’m kicking myself because I’ve done the timing belt water pump to my previous 96 4runner. Not a job that’s far out of my scope of abilities. I just don’t have a garage or good place to work on my truck at the moment and decided to trust them from a friends recommendation.
